The Rupee Foradian 3.0 font introduces a simplified rupee symbol glyph, fixes an overlapping issue with horizontal lines at font size 10, and includes an automatic Windows installer. Users can install the font by running the installer executable, then select "Rupee Foradian" from word processing applications and press the key above Tab to insert the rupee symbol. Non-Windows users should manually install the TTF file and visit the Foradian blog for help. The font can also be inserted by typing 0096 while holding Alt.
